ABSTRACT:
An acoustic transducer with partially driven area of the diaphragm such that the driving forces are asymmetric with respect to the frame axis of symmetry or angled with respect to edges of diaphragm support frame to provide uniform frequency response of the transducer. The elongate magnet sections surround portions of the diaphragm with a fringing magnetic field within which a circuit of conductor strips is positioned such that selectively excited vibration modes of the diaphragm provide a smooth frequency response.
